Classes in Python

Classes

A class is a blueprint for an object.

Object-oriented programming is an influential, powerful, and expressive programming abstraction. The programmer thinks in terms of classes and objects. An object contains specific data and provides the functionality specified in the class.

Say you are programming a game to let you build, simulate, and grow the cities. In object-oriented programming, you represent all things (buildings, persons, or cars) as objects. For example, each building object stores data such as name, size, and price tag. Additionally, each building provides a defined functionality, such as calculate_monthly_earnings(). In short, object-oriented programming helps you to write readable code.

A class encapsulates data and functionality: data as attributes and functionality as methods. It is a blueprint for creating concrete instances in memory.
